ions, or the like.

Another and more specific object ofi ny invention is to generally lmprove, slmphfy and cheapen the construction of such de-.

vlces.

Other. and further objects of my invention willbecome readily apparent, to persons skilled in the art, from a consideration of the following description when taken in conjunction with the drawings, -where1n:-

Figure 1 is .a plan view of a completed mattress structure showing parts broken away to expose the several features thereof. Fig. 2 is a section'taken on line 22 of Fig. 1. Fig. 3 is a section taken on line 80 3-3 of Fig. 1.

' In all the views the same reference characters are employed to indicate similar parts. l

One of the prime objects I have mview is the provision of a spring structure that i is a complete entity within itself, mdependently of the upholstery, such as hair, felt, batting, or the like, and the covering thereof that may be subsequently applied to the 40 spring structure, as when making mattresses, cushions or upholstering furnlture. Spring structures, of aclass to which my invention relates, when made separately from and independently of the subsequently applied upholstery material may be constructed by a class'of mechanics especially well skilled in that particular branchof the art and when completed may be furnished to others who are better skilled in the subsequent application of the upholstering materials to the spring structure, thusconfining to the artisans the work which by prior training they are best adapted toper orm, thereby to cheapen the construction efii- 65 ciency of the completed article and theconvenienoe of manufacture.

' p Application filed June 1, 1915. Serial No. 31,366.

While I have herein shown my spring structure as it will appear when incorpo rated in a mattress, it is to be understood that the spring structure of itself is separate and independent of the subsequently to be applied material necessary for the construction of a mattress. And while my invention is equally applicable to other structures than mattresses, as for instance, cushions or the like, I have shown it herein in association with a mattress as one means for clearly disclosing the invention and its use. In carrying my invention into effect I provlde a top and bottom sheet, 5 and 6,

respectively, of burlap or other suitable fabric, of suitable width and length for the structure to be made, and sew the longitu-' dinal edges together as at 7, and at suitable intervals, I attach the two sheets to ether,- as at 8, as by means of a tufting stitci ton on the like. I prefer to place these stitched portions at uniformly spaced apart intervalsin longitudinal rows and after one row has been thus stitched I prefer to insert the springs 9-9 between the fabric sheets 5 and 6, as clearly shown in Figs. 2 and 3. The extension of the springs 9 -9 but- A has theefi'ectto separate the covers or-sheets 5 and 6 and to deform the intervening portion into funnel shaped pockets 10, with their apices connected together, thereby causing the fabric to be drawn down be' tween adjacent springs, complete pockets being formed in the space between every four angularly disposed s rings thereby placing at least two layers 0 fabric between adjacent spring surfaces. The distance of separation between the stitched together parts 88 will determine the thickness of the spring structure and to some extent'the width of the conical pockets 1010. After the springs have been inserted behind the first row of stitching 88, a second row of stitching 88 is made, in front of the first row, and a second series or row of springs is placed behind the second row of stitching. This is a convenient way of making the structure, although the entire stitching together at intervals of the upper and lower surfaces of the spring structure, or sheets 5 and 6, may be completed and the springs subsequently inserted by being collapsed with a'proper pair of tongs or other instruments, and pushed into their proper posit1ons.- 7

'After the springs have been placed between the sheets and 6, in the manner heretofore described, I then prefer to pass cordsunder the wire of one 5 ring, as at13, thence 18-18, in a similar manner, transversely of through the doubled fa ric or inwardly projecting node 14, and under the wire 15, of the adjacent spring, and then up through the fabric again as at 16, and secured thereto, as at 17, toa marginal spring, or in the case of an intermediate spring passing it across the upper surface of the said spring and through the fabric and under the opposite side of the terminal coil thereof, as heretofore described. I then pass cords, or tapes the cords or tapes 1111 and secure them as at 19, in the same 'way', having passed them through the fabric and under the terminal rings of adjoining springs as in the first instance. lhe tapes or cords 11- 11 and 1818 serve as an additional means for holding the springs in their relative positions.

In applying hair, felt or cotton, asin making a mattress 20, the conical pockets 10 are preferably to be filled with such material and the layers 21 and 22,- are to be applied between the spring structure and the final coverings 23 and 24 of the mattress. The subsequent application of this upholstering material, to my spring structure, however, is entirelyindependent of said structure and may be applied thereto and removed therefrom without affecting the said spring structure. I

A spring structure when made in accordance with my invention is very resilient and yielding, is noiseless, as there is no contact of any two parts of moving metal constituting the springs or other portions of the desprings,

neoaeoe vice, and will remain of uniform thickness, owing .to the connected adjacent conical pockets 101O serving as means for preventing unequal expansionof the springs, but permitting their contraction orcompression without imposing any undue resistance thereto.

While l have herein shown.a single embodiment of my invention for the purpose of clear disclosure it is evident that changes may be made in the formation and relation of the parts within the scope of the appended claim.

Having described my invention, what I claim is A spring structure comprising a topand bottom sheet of fabric joined at their edges to form aspring inclosing envelop, a plurality of coil springs arranged in parallel rows within the envelop with their ends abutting against the top and bottom sheets, said sheets being fastened together at spaced apart intervals to provide inwardly taperpockets between each four adjacent the fabric being doubled in between adjacent spring ends to stretch the fabric tight across the spring ends and form nodes therebetween extending below the spring ends, and cords, crossing the major portions of the spring ends outside the fabric at right angles and passing through the fabric to the inner side thereof near the spring coils and through doubled-in folds of fabric at points inside the plane of the end coils to secure the spring ends to the fabricat the points of cord penetration.

In testimony whereof I hereunto set my hand in the presence of two subscribing witnesses. V
